XTranslateCoordinates(3X11)
X11R6


NAME
  XTranslateCoordinates - translate window coordinates

SYNOPSIS
  Bool XTranslateCoordinates(display, src_w, dest_w, src_x, src_y,
  dest_x_return, dest_y_return, child_return)
	  Display *display;
	  Window src_w, dest_w;
	  int src_x, src_y;
	  int *dest_x_return, *dest_y_return;
	  Window *child_return;

ARGUMENTS
  child_return
      Returns the child if the coordinates are contained in a mapped child of
      the destination window.

  dest_w
      Specifies the destination window.

  dest_x_return

  dest_y_return
      Return the x and y coordinates within the destination window.

  display
      Specifies the connection to the X server.

  src_w
      Specifies the source window.

  src_x

  src_y
      Specify the x and y coordinates within the source window.

DESCRIPTION
  If XTranslateCoordinates returns True, it takes the src_x and src_y
  coordinates relative to the source window's origin and returns these
  coordinates to dest_x_return and dest_y_return relative to the destination
  window's origin. If XTranslateCoordinates returns False, src_w and dest_w
  are on different screens, and dest_x_return and dest_y_return are zero. If
  the coordinates are contained in a mapped child of dest_w, that child is
  returned to child_return. Otherwise, child_return is set to None.

  XTranslateCoordinates can generate a BadWindow error.



DIAGNOSTICS
  BadWindow
	  A value for a Window argument does not name a defined Window.
